Abstract:
Mutations in the Saccharomyces cerevisiae SPT3 gene have dramatic effects on the expression of Ty elements and genes adjacent to the element. The SPT3 gene is essential for Ty transposition, because transposition of chromosomal Ty elements ceased when the SPT3 gene was replaced with the frameshift mutation spt3-101. Presumably, the elimination of transposition was due to the effect of the SPT3 gene product on Ty transcription; the transcripts of chromosomal Ty elements were largely abolished in the spt3-101 strain (F. Winston, K. J. Durbin, and G. R. Fink, Cell 39:675-682, 1984). Ty transcription in an spt3-101 strain could be reestablished by introduction of the pGTyH3 plasmid, in which transcription of the Ty element TyH3 is under the control of the GAL1 promoter; these plasmid-derived Ty transcripts were SPT3-independent. Ty transposition resumed after galactose induction in spt3-101 strains containing the pGTyH3 plasmid. In spt3 mutants nearly all of the resulting transposition events derived from pGTyH3 plasmids and not from chromosomal elements.

Abstract:
Background Panulirus argus is an ecologically relevant species in shallow water hard-bottom environments and coral reefs and target of the most lucrative fishery in the greater Caribbean region. Methods This study reports, for the first time, the genome size and nuclear repetitive elements, including the 45S ribosomal DNA operon, 5S unit, and microsatellites, of P. argus. Results Using a k-mer approach, the average haploid genome size estimated for P. argus was 2.17 Gbp. Repetitive elements comprised 69.02% of the nuclear genome. In turn, 30.98% of the genome represented low- or single-copy sequences. A considerable proportion of repetitive sequences could not be assigned to known repeat element families. Taking into account only annotated repetitive elements, the most frequent belonged to Class I-LINE which were noticeably more abundant than Class I-LTR-Ty- 3/Gypsy, Class I-LTR-Penelope, and Class I-LTR-Ty-3/Bel-Pao elements. Satellite DNA was also abundant. The ribosomal operon in P. argus comprises, in the following order, a 5′ ETS (length = 707 bp), ssrDNA (1,875 bp), ITS1 (736 bp), 5.8S rDNA (162 bp), ITS2 (1,314 bp), lsrDNA (5,387 bp), and 3′ ETS (287 bp). A total of 1,281 SSRs were identified.

Abstract:
Background Hoplolaimus galeatus is a plant-parasite nematode with a broad range of hosts. This nematode is known to damage cotton, corn, and soybean crops. Hoplolaimus galeatus is also an economically important pest of turfgrasses. Despite its economical importance, no genomic resources exist for this parasite. Methods Using 300 bp paired-end short read sequencing, this study estimated genome size, analyzed a nearly complete mitochondrial chromosome, and explored nuclear repetitive elements, including microsatellites, in H. galeatus for the first time. The phylogenetic placement of H. galeatus in the superfamily Tylenchoidea was also examined. Results The average haploid genome size estimated using a k-mer approach was 517.69 Mbp. The partially assembled mitochondrial genome of H. galeatus is 16,578 bp in length and comprised of 11 protein-coding genes, two ribosomal RNA genes, and 16 transfer RNA genes. A maximum likelihood phylogenetic analysis confirmed the monophyly of the genus Hoplolaimus and the superfamily Tylenchoidea. Repetitive elements constituted 50% of the nuclear genome while half of the genome represented single- or low-copy sequences. A large portion of repetitive sequences could not be assigned to known repeat element families. Considering only annotated repetitive elements, the most ubiquitous belonged to Class II- Subclass 2-Maverick elements, Class I-LTR-Ty-3/Bel-Pao elements, and satellites. 45S ribosomal DNA was also abundant and a total of 36 SSRs were identified.This study developed genomic resources for the plant-parasitic nematode Hoplolaimus galeatus that will contribute to the better understanding of meta-population connectivity and putative genomic mechanisms involved in the exploitation of the broad range of host plants used by H. galeatus.

Abstract:
Vzájemné kontakty kultur vytvářejí prostor pro řadu zkušeností. Jednou z nich je i kulturní šok, který pramení z početných stresorů. Ty se objevují po kontaktu s jinou kulturou. Kulturní šok je reakcí na vystavení neznámým a neočekávaným okolnostem a reprezentuje psychologický dopad adaptace na novou kulturu. Existují však způsoby zvládání kulturního šoku a můžeme identifikovat pozitivní elementy, které ovlivňují tento fenomén. Tato práce předkládá, jak organizace občanské společnosti může ovlivnit zkušenost s kulturním šokem. In media res článek analyzuje aktivity Diecézní Charity Brno ve vztahu ke kulturnímu šoku. Uvádíme, že organizace občanské společnosti přispívají k překonání kulturního šoku.

Abstract:
It is known that the value of the exponential sum [Formula: see text] can be derived from the estimate of the cardinality |V|, the number of elements contained in the set [Formula: see text] where [Formula: see text] is the partial derivatives of [Formula: see text] with respect to [Formula: see text]. The cardinality of V in turn can be derived from the p-adic sizes of common zeros of the partial derivatives [Formula: see text]. This paper presents a method of determining the p-adic sizes of the components of (ξ,η) a common root of partial derivative polynomials of f(x,y) in Zp[x,y] of degree five based on the p-adic Newton polyhedron technique associated with the polynomial. The degree five polynomial is of the form f(x,y) = ax5 + bx4y + cx3y2 + sx + ty + k. The estimate obtained is in terms of the p-adic sizes of the coefficients of the dominant terms in f.

An attempt has been made to explain the correlation between various ionic concentrations. The maximum concentrations of sulfate, nitrate and hydrogen ions in rainwater are observed during winter season. When classified by season the wet deposition flux for all the ions is greatest in the monsoon season during which precipitation is substantially high. A tendency for increase in acidic deposition is observed at both the stations. The volcanic activity at Barren island appears to influence the chemical composition of rainwater at Portblair. The annual wet deposition of SO42- ranged from 15.6 kg ha-1 yr-1 at Minicoy to 25.5 kg ha-1 yr-1 at Portblair, and the corresponding amounts of NO3- deposited ranged from 38.0 kg ha-1 yr-1 at Minicoy to 74.6 kg ha-1 yr-1 at Portblair. Of the cations Na+ and Ca2+ are the elements deposited in largest quantities followed by Mg2+ and K+.

Abstract:
Katakan x = {xi, x2,...,xn} vektor dalam ruang Zn dengan Z menandakan gelanggang integer dan q integer positif, f polinomial dalam x dengan pekali dalam Z. Hasil tambah eksponen yang disekutukan dengan f ditakrifkan sebagai S (f;q) = exp (2πif (x)/ q) yang dinilaikan bagi semua nilai x di dalam reja lengkap modulo q. Nilai S(f;q) adalah bersandar kepada penganggaran bilangan unsur |V|, yang terdapat dalam set V = {x mod q | fx = 0 mod q} dengan fx menandakan polinomial-polinomial terbitan separa f terhadap x. Untuk menentukan kekardinalan bagi V, maklumat mengenai saiz p-adic pensifar sepunya perlu diperolehi. Makalah ini membincangkan suatu kaedah penentuan saiz p-adic bagi komponen (ξ,η) pensifar sepunya pembezaan separa f(x,y) dalam Zp[x, y] berdarjah lima berasaskan teknik polihedron Newton yang disekutukan dengan polinomial terbabit. Polinomial berdarjah lima yang dipertimbangkan berbentuk f(x,y) = ax5 + bx4y + cx3y2 + dx2y3 + exy4 + my5 + nx + ty + k. Kata kunci: Hasil tambah eksponen, kekardinalan, saiz p–adic, polihedron Newton Let x = {xi, x2,...,xn} be a vector in a space Zn with Z ring of integers and let q be a positive integer, f a polynomial in x with coefficients in Z. The exponential sum associated with f is defined as S (f;q) = exp (2πif (x)/ q) where the sum is taken over a complete set of residues modulo q. The value of S (f;q) has been shown to depend on the estimate of the cardinality | V |, the number of elements contained in the set V = {x mod q | fx = 0 mod q} where fx is the partial derivatives of f with respect to x. To determine the cardinality of V, the information on the p-adic sizes of common zeros of the partial derivatives polynomials need to be obtained. This paper discusses a method of determining the p-adic sizes of the components of (ξ,η) a common root of partial derivative polynomials of f(x, y) in Zp[x, y] of degree five based on the p-adic Newton polyhedron technique associated with the polynomial. The quintic polynomial is of the form f(x,y) = ax5 + bx4y + cx3y2 + dx2y3 + exy4 + my5 + nx + ty + k. Key words: Exponential sums, cardinality, p–adic sizes, Newton polyhedron
